ISO affordable 10kg bag of organic brown rice

I've been buying a 10kg bag of Tsuru Mai® Brown rice for less than $15/20 from a Chinese supermarket in Chinatown east for the past few years, but I'm hoping to find an affordable brand of organic brown rice (medium-short grain preferred) to switch to. We eat a lot of rice, so I'm not interested in the small 2kg bags of rice you find in most grocery stores. Strictly Bulk at Pape and Danforth sell Lundberg organic brown rice in bulk and they said I could buy the large bag for 10% off the cost of the bulk rice, but wanted to see if there were any other cheaper options out there... Thanks.
